Abstract (en)
The present invention relates to a pouch-shaped battery cell including an electrode assembly, a pouch-shaped battery case configured to receive the electrode assembly, and an electrode lead extending from the electrode assembly, a part of the electrode lead protruding outwards from the pouch-shaped battery case, wherein a sealed portion is formed at an outer periphery of the pouch-shaped battery case, a venting adjustment means is mounted to a part of the sealed portion in a direction in which the electrode lead protrudes, and the venting adjustment means is configured to adjust opening and closing of the sealed portion having the venting adjustment means mounted thereto based on the pressure of gas in the pouch-shaped battery case.
